There's always that moment when you've got a plate of food, a laptop, and nowhere to put either, because the only surface in the room is the coffee table and it's already covered in mail you haven't dealt with. A small table fixes that one problem so completely that you wonder why you waited a year to buy one.
Color wise, the easiest ones to live with are the quiet woods, a honey oak or a worn looking walnut, because they don't demand attention and they go with whatever you buy next, which matters when you're furnishing room by room instead of all at once. White and black both work too, but they show every water ring and every dust bunny within about four days, so if you're not someone who wipes things down often, go with a finish that already looks a little lived in. As for wear, real wood or a solid veneer will pick up scratches and the occasional ring from a cold glass, and honestly that just becomes part of it, a sort of record of the house. Wipe spills fast, use a coaster if you can be bothered, and every few months a little furniture polish will keep it from looking tired. The cheaper pressed wood versions don't age so much as they just give up, usually around the edges first, where the laminate starts to peel like a bad sunburn.
When you're buying one in person or checking it the day it arrives, put your hand flat on top and press down near the edge, a table with any wobble at all will only get worse once it's holding weight every day. Check the legs are actually even on your floor, not just the showroom floor, and if it's flat pack, look at how the leg attaches, because a leg that screws into a solid block will outlast one glued into particleboard by years. Open the drawer if it has one. If it sticks in the shop, it will stick forever in your house.
Scale is where people go wrong. A small table that's the right size leaves you room to walk past with a laundry basket without turning sideways, and a wrong sized one crowds the one good chair in the room until nobody wants to sit in it. In a smaller space, lower and narrower almost always beats anything with bulk, even if the bulkier one looks nicer in a photo.
Next to it, I'd put a lamp with a warm bulb and one object you actually like looking at, not a basket for things you mean to deal with later.
